Christian Haudum	62176339c4	Bloom querying: Propagate line filters from querier to bloom filter (#11492 ) In order to query the bloom filters with the search strings from the user query, we need to propagate the line filters through the different implementations of the store, namely through the GetChunks function. In order to avoid converting data structures, the line filter from the syntax tree is used as custom protobuf type, because it is passed from querier to index gateway and from index gateway to bloom gateway. So far, the line filters request have not been tokenized to n-grams. This PR adds the ability to read the n-gram length from the block schema at query time and tokenizes the line filters from the input just ahead of searching the block.

Christian Haudum	2b6bdc2a29	chore(storage): Simplify store interfaces and abstractions (pt 2) (#10454 ) What this PR does / why we need it: * Remove preemptive interface from indexReaderWriter and make it an exported struct * Compose IngesterStore and QuerierStore The ingester and querier do not require a store that implements the full interface, but can accept stores that are a subset of the interfaces. Therefore we can make specific interfaces that are accepted by the ingester and querier constructors. * Split up ChunkFetcher interface This commit splits the ChunkFetcher interface into a ChunkFetcher and a ChunkFetcherProvider interface. This has the advantage that methods can allow accepting smaller interfaces. This commit also renames the `GetChunkRefs()` method of the ChunkFetcher interface into `GetChunks()`, because it returns a `[][]chunk.Chunk`, not a `[]chunk.ChunkRef` type.

Kaviraj Kanagaraj	bbfb13c3e4	Pin `chunk` and `index` format to `schema` version. (#10213 ) We pin all three `Chunk`, `HeadBlock` and `TSDB` Version to `schema` version in period config. This is the following mapping (after being discussed with @owen-d and @sandeepsukhani ) `v12` (current existing schema) - ChunkFormatV3 (UnorderedHeadBlock) + TSDBv2 `v13` (introducing new schema) - ChunkFormatV4 (UnorderedWithNonIndexedLabelsHeadBlockFmt) + TSDBv3 Note the new schema `v13` supports the latest chunk and index format. NOTES for Reviewer 1. General approach is we removed the idea of `index.LiveFormat`, `chunkenc.DefaultChunkFormat` and `chunkenc.DefaultHeadBlockFmt` and made following two changes. These variables were used before to tie chunk and tsdb formats specific to Loki versions. This PR remove that coupling and pin these formats to `schema` version instead. 1. These variables were replaced with explicit chunk and index formats within those packages (and it's tests) 2. If these variables were used outside it's own packages say by ingester, compactor, etc. Then we extract correct chunk and index versions from the `schema` config. 2. Add two methods to `periodConfig`. (1) `ChunkFormat()` returning chunk and head format tied to schema (2) `TSDBFormat()` returning tsdb format tied to schema. 2. Other ideas I thought of doing but didn't end up doing is make `ChunkFormat` and `IndexFormat` as separate type (rather than `byte` and `int` currently. Similar to `HeadBlockFmt` type). But didnt' do it eventually to keep the PR small and don't want to complicate with lots of changes. 4. Moved couple of test cases from `chunkenc` to `config` package, because the test case was actually testing methods on `schemaconfig` and it was creating cycling dependencies. --------- Signed-off-by: Kaviraj <kavirajkanagaraj@gmail.com>	2 years ago
Owen Diehl	f53498c4aa	allows filter-only matchers in series endpoint (#10269 ) We already allow empty matchers `{}` as a special case in series queries to return all series.

Danny Kopping	beed298549	Dynamic client-side throttling to avoid object storage rate-limits (GCS only) (#10140 ) What this PR does / why we need it: Across the various cloud providers' object storage services, there are different rate-limits implemented. Rate-limits can be imposed under multiple conditions, such as server-side scale up (ramping up from low volume to high, "local" limit), reaching some defined upper limit ("absolute" limit), etc. We cannot know apriori when these rate-limits will be imposed, so we can't set up a client-side limiter to only allow a certain number of requests through per second. Additionally, that would require global coordination between queriers - which is difficult. With the above constraints, I have instead taken inspiration from TCP's [congestion control algorithms](https://en.wikipedia.org/wiki/TCP_congestion_control). This PR implements [AIMD](https://en.wikipedia.org/wiki/Additive_increase/multiplicative_decrease) (Additive Increase, Multiplicative Decrease), which is used in the congestion _avoidance_ phase of congestion control. The default window size (object store requests per second) is 2000; in other words, we skip the "slow start" phase. The controller uses the Go [`rate.Limiter`](https://pkg.go.dev/golang.org/x/time/rate), which implements the token-bucket algorithm. To put it simply: - every successful request widens the window (per second client rate-limit) - every rate-limited response reduces the window size by a backoff factor (0.5 by default, so it will halve) - when the limit has been reached, the querier will be delayed from making further requests until tokens are available	2 years ago

Travis Patterson	db97058a84	Series volume endpoint (#9704 ) This changes the `label_volume` endpoint to the `series_volume` endpoint.

Travis Patterson	a98b7ebaf4	Hide duplicates caused by stream sharding (#7005 ) As streams are sharded and resharded across different ingesters, the likelihood of duplicate logs being ingested increases dramatically. This removes duplicates at query time by dynamically removing the `__shard_stream__` label for both log and sample queries so the `stream hash` used by the `MergeEntryIterator` will match when doing comparisons for duplicates. The `stream hash` is created in either the `store` or `ingester instance` at query time so the labels are removed there. Additionally, the `MergeEntryIterator` has been modified to remove duplicates in a stream rather than just across streams. For completeness, `__shard_stream__` has also been removed from Label and Series Queries.	3 years ago

Cyril Tovena	049c7acc12	Improve logql parser allocations. (#2927 ) * Improve logql parser allocations. Also moving labels parsing into logql package, and I'm not shy to say that promql is faster for this. So we're using promql for parser, it's faster because their lexer is more sophisticated than ours. Result are impressive. ``` ❯ benchcmp before.txt after.txt benchmark old ns/op new ns/op delta Benchmark_ParseLabels-16 24394 8745 -64.15% benchmark old allocs new allocs delta Benchmark_ParseLabels-16 156 20 -87.18% benchmark old bytes new bytes delta Benchmark_ParseLabels-16 24976 2099 -91.60% ``` Combined with #2926, I think we should be able to get rid of `util.ToClientLabels`.

Ed Welch	b8a61357bb	Loki: fix batch iterator error when all chunks overlap and chunk time ranges are greater than query time range (#2484 ) * Fixes a bug where if all chunks are fetched before finding a non-overlapping chunk, and the chunk from/through times are outside of the query request times, we would incorrectly set the iterator from/to bounds leading to missing logs in the query. * uncomment `includesOverlap` which was commented during testing and not fixed by mistake.	5 years ago
